By the end of 2021, scientists had presented perovskite silicon tandem solar cells with an efficiency close to 30 percent. This value was a world record for eight months, a… Read More »Tandem solar cells with perovskite: Nanostructures help in many ways
An improvement to a Nobel Prize-winning technology called a frequency comb enables it to measure light pulse arrival times with greater sensitivity than was previously possible — potentially improving measurements… Read More »To break new ground with frequency combs, an innovation plays with the beat
Exposure in utero to a specific flame retardant, or to its individual brominated (BFR) or organophosphate ester (OPFR) components, resulted in altered brain development in newborn rats. Go to Source… Read More »Gestational exposure to flame retardant alters brain development in rats
The mystery of the origin of hydrocarbons found in extraterrestrial environment may finally be resolved, thanks to a technique based on a 13C-13C abundance analysis. By measuring the abundance of… Read More »Using carbon-carbon clumping to detect the signature of biotic hydrocarbons
